ABSTRACT:
Apparatus for stacking selected layers of products on a pallet comprises an upstanding frame having two side walls, a back wall forming a close with the side walls, an open entry side and an open uppermost end defined by peripheral frame members. Clamp means circumscribe the uppermost end in unobstructive overhead relation within the close and surrounding frame members to provide an inwardly directed clamping pressure between the side walls and between the back wall and frame members positioned above the entry side. Clamping pressure is generated by inflatable air bags positioned between the peripheral frame members and pressure plates facing inwardly of the close. Layers of products from successive pallet loads are placed by a forklift truck into the apparatus through the open side. A selected layer is raised and supportively clamped. The remaining pallet load is lowered and withdrawn. Successive pallet loads of different products are placed into the apparatus and raised to engage the lowermost surface of the previous clamped layer which is then released. The combined load is raised to the next selected layer and reclamped, the remainder being lowered and withdrawn. Loads extending above the apparatus are confined within a safety cage in a further embodiment which also includes a safety curtain to support the load in the event of clamp means failure. On completion of stacking, clamping pressure is released and the entire load of assorted product layers is lowered and withdrawn.
